Are you ready to upgrade your Brenspeed 475C package to the Brenspeed
CJ519 to take your Mustang to the next level?

The
Brenspeed CJ519 package is designed for 2011 to 2014 manual and
automatic transmission mustangs. Our CJ519 package has extensive
development on the street and at the track and provides a drastic
improvement in power over a factory stock 5.0L Mustang and improvement
over the 475C.

Cobra
Jet spec 1 7/8" stainless steel long tube headers. Our CJ519 headers
are the same spec as found on the Cobra Jet and built in the same
facility as Cobra Jet headers. The major difference is Cobra Jet
Mustangs have a 3.5" dump at the header collector. This is not feasible
for a street car. Our CJ519 spec headers collect at 3" and are fitted
to a catalytic or off road H or X pipe.

Hybrid
Brenspeed CJ Engine Calibration. Our CJ519 package includes a Brenspeed
CJ inspired engine calibration. Many aspects of the CJ will be found in
our drag strip only calibration. Our street calibration is tamed down
for street use. The package includes both the street and drag strip
ready calibrations.

170
degree thermostat for high performance engines, providing high flow to
your radiator by mid-180 temps while still providing good all season
performance.

Also
included is
a Custom Brenspeed CJ519 Graphics Package available in 4 different
finishes. Gloss Black, Matte Black, Silver, and
White. Exclusive to
CJ519 owners only!

There
have been several variations of the Cobra Jet since 2008. Most every
example was supercharged but in 2013 Ford released the Naturally
Aspirated Cobra Jet Mustang. The Naturally Aspirated Cobra Jet inspired
us to develop a package using Cobra Jet spec parts for that individual
who was looking for over 500 HP Naturally Aspirated horsepower and
loved the Cobra Jet History. The goal was a fast naturally aspirated
car that retains as much Cobra Jet heritage as possible yet remains a
street car.

Keep Your Air Filter Dry
Constructed from a thick foam rubber, this Roush Insert Plug installs
into the underside hood insulator to block rain water from entering
your aftermarket cold air intake or open element air filter.

Heat Extractor Compatible
The Roush insert plug is designed to only block off the lower portion
of the vent opening so it still allows underhood engine heat to escape
through the factory hood extractors.
